Honda has released full specifications for its upcoming the CRF250L, a dual-sport with an engine based on the CBR250R‘s powerplant with a fuel efficiency of 104 mpg.

Set to launch in Japan in May and Europe in the summer, the 2012 Honda CRF250L replaces the CRF230L in Honda's repertoire. North American availability hasn't been officially been announced, though Honda Canada is expected to introduce the CRF250L in the summer.

To produce the CBR250R, Honda developed the fuel-injected liquid-cooled 250cc four-stroke DOHC Single engine to have very low internal friction, employing a number of innovations such as an offset cylinder and roller rocker arms in the valve train. The CRF250L's engine maintains the same 76mm bore, 55mm stroke and 10.7:1 compression ratio. Honda claims a peak output of 23hp at 8500rpm and 16 ft-lb. at 7000rpm from the CRF250L's engine.
